The Cartographers’ Guild is a forum created by and for map makers and aficionados, a place where every aspect of cartography can be admired, examined, learned, and discussed. Our membership consists of professional designers and artists, hobbyists, and amateurs—all are welcome to join and participate in the quest for cartographic skill and knowledge.

Although we specialize in maps of fictional realms, as commonly used in both novels and games (both tabletop and role-playing), many Guild members are also proficient in historical and contemporary maps. Likewise, we specialize in computer-assisted cartography (such as with GIMP, Adobe apps, Campaign Cartographer, Dundjinni, etc.), although many members here also have interest in maps drafted by hand.

Species Migration Map

Ok well I offered this up in the evolution map thread. There seemed to be some interest in such a map. So as not to derail that thread we will move the question over here.

Would you be interested in a contest where you design a map and then plot migration routes for a species as it spreads out from its cradle into new parts of the globe? The most common versions of this type of map are the human migration routes with all the arrows moving out of Africa. However, someone else suggested using gradients to represent different times in history during the migration. I am sure there are also many other ways you could show how your group traveled outwards from their birthplace.

Edit: Bartmoss has a very good point so then not just any specific migration map but any map that shows the travel and wanderings of a group. It could be a new species, the colonists of an empire, etc etc.

There's no reason* to make such a map in 2D. If you animate a 2D map across time, that's a third dimension. Or if you animate a spatially 3D map across time, that's 4 dimensions. Add a scrubber and a proximate-data fader, and you're gettin' really sexy!

*Except the cost in time. Or the cost in materials/technology. Or a flat-out lack of ability, which would be my excuse.

I like it, but I would suggest extening it: Make it a general migration map, perhaps? So you could track either a species, or the expansion of the colonies in the new world, or mankind as it settles near-earth solar systems? Just a suggestion.

I think that would work and would be within the scope of a migration map.
